I own the PX4 in 9mm and greatly enjoy the gun. It keeps suprising me with its accuracy. It is a nice looking gun, comfortable to shoot, and easy to clean. Only thing I haven't quite adjusted to is the long trigger pull on the first (double action) shot.
I've had no FTF or FTE's. And neither has my wife. She will get stovepipes on her Glock 19 after shooting a three or four magazines as her hand tires out, but so far hasn't had that problem with the PX4.
I've never shot an FNP, so no advice there. Hopefully, you'll be able to try one of each before buying.
Never argue with drunks or crazy people.
